What is true of this colour, and of no other

  • No other named colour in the set is within ΔE00 2 of it — it stands alone.
  • It sits exactly on the sRGB boundary: at this lightness and hue the gamut has nothing left, and a wider display would show a more colourful version of it.
  • As text on white it measures APCA Lc 55.2; on black, Lc -46.6. The sign is the polarity, which the WCAG ratio discards.
  • Built into an eleven-step scale, 10 of the 10 adjacent pairs stay ΔE00 2 apart — see the ramp.
  • protanopia and deuteranopia and tritanopia shift it by ΔE00 6.2 and 6.1 and 31.7 — no red cone.
